Title: Apparatus for synchronizing a remote television signal source
IPC: H03K5/156
Filed: 1961-07-21
Abstract: 961,228. Automatic phase control systems; television. FERNSEH G.m.b.H. July 21, 1961 [July 23, 1960] No. 26492/61. Drawings to Specification. Headings H3A and H4F. At television camera stations remote from a television central control station synchronizing pulses are generated of timing advanced relative to synchronizing pulses received at the cameras from the central station by twice the time of transit of pulses between the two stations so that sync. pulses transmitted back to the centre station, along with video signals, are in phase synchronism with the central station master synchronizing pulses. To this end, line and vertical sync. pulses are derived at the cameras from a composite video and sync. signal transmitted from the central station and the line sync. pulses phase compared with local line sync. pulses generated and passed to a phase detector circuit through a delay network of delay equal to twice the constant time of transmission of signals between the stations. The phase detector output may control a pulse generator of twice line recurrence frequency from which the line and vertical sync. pulses are derived by frequency division. The received vertical, and local vertical sync. pulses, may also be phase compared in a bi-stable circuit with output temporarily altering, e.g. from 5 to 6, the division ratio of the frequency divider until vertical sync. coincidence is produced, and the local vertical pulses may be applied to the bi-stable circuit as before through a delay also equal to twice the signal transit time. Alternatively, a coincidence circuit may replace the bi-stable circuit, with output controlling a gate circuit gating out one or more of the line sync. pulses applied to the frequency divider until the frequency divided vertical sync. pulses applied to the phase detector correspond in tuning with those received from the master station.

Filed: 1958-08-20
Abstract: 876,028. Control of several A.C. motors. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. Aug. 20, 1959 [Aug. 20, 1958], No. 26816/58. Class 38 (3). [Also in Group XL (a)] The movement of nuclear reactor control rods is controlled by supplying the rod-actuating motors sequentially, each with a predetermined number of cycles from a low frequency generator. A continuously rotating induction motor 21 drives the rotor 71 of an induction regulator through one of four clutches 28, 29, 35, 36 according to direction and speed required. The induction regulator is connected through transformers and biased rectifiers to provide outputs X, Y 90 degrees apart, with a neutral N, as described in Specification 842,649. A control circuit for the " odd " numbered rods is described, including transfer of low frequency supply from one motor (or group of motors) to the next by the closing of a cam-operated switch 57 when 400 cycles have been supplied. During lowering of the rods the movement is not interrupted, but during raising a further manual operation is necessary to start a newly connected motor (or group of motors). A second cam-operated switch 55 ensures that the induction regulator stops in the negative halfcycle. A limit switch operated by a rod at the top of its travel short circuits any motor attempting to overwind a rod, a free-wheel device protects when a motor attempts to lower a rod at the bottom. To shape the neutron flux pattern certain rods may be kept in position, their actuating motors being by-passed. To prevent rapid raising of the rods, an idler pinion 44 may be removed. Specifications 817,332, 820,460, 832,367, 833,532, 835,448 and 848,521 also are referred to.

Title: Multi-processor processing system having inter-processor interrupt transfer apparatus
IPC: G06F13/26
Filed: 1971-04-19
Abstract: 1352577 Interrupt handling BURROUGHS CORP 19 April 1971 [9 April 1970] 26829/71 Heading G4A A data processing system includes first and second means for requesting an interrupt condition to be processed, first and second interrupt handlers normally respectively associated with the first and second interrupt requesting means and each having an interruptable and a non- interruptable state and being operative in the latter state to transfer an interrupt request from its associated interrupt requesting means to the other interrupt handler. Each processor of a multiprocessor system operates in one of two states, viz normal and control, the operating state being denoted by a flag flip-flop. In the control state the processor is non-interruptable and is handling, e.g. input/ output transfers. As shown two input/output channels are connected via respective multiplexors to respective interrupt handlers with which they are normally associated. The interrupt handlers may be self contained hardware or program controlled devices. Each handler has an associated left-to-right (LTR) and rightto-left (RTL) transfer circuit which consists of a number of gates and which assigns interrupts to the processors 7A and 7B. Control signals, which may if required be changed, are supplied to the gates to determine the normal allotment of interrupts to the processors. The occurrence of an interrupt normally associated with a handler in a non-interruptable state causes operation of the transfer circuits to re-allot the interrupt to a different handler and processor. Where more than two processors are involved the re-allotment is made on a system of priorities, the highest priority available processor being selected. The Specification briefly describes the organization within each processor. First in-last out stacks are provided for storing operands and instruction sequences. The stacks are accessed from a register which includes a field specifying the top word in the stack which is then accessed word by word using a counter. Each stack may specify the next in the sequence. For entering a new procedure, e.g. in response to an interrupt, the point reached in the interrupted sequence together with intermediate results &c. are stored in a stack specified by a return control word and the new procedure is entered by means of a program control word which may itself be a return control word. The input/output units may be magnetic tapes, discs or card readers and the main memory 12 may be a magnetic core.

Moulding resins.-To decorate moulded articles formed from synthetic resinous condensation products a decorative sheet of paper, fabric &c. impregnated with a viscous solution of the intermediate condensation product containing also an agent for accelerating the preliminary drying is moulded in or upon the article. The article is then subjected to heat and pressure. The accelerating agents may consist of hexamethylenetetramine, salts of ammonia &c. The impregnating solution may be prepared by the reaction of 1 molecular proportion of urea with 2 molecular proportions of formaldehyde, 2-4 per cent of hexamethylenetetramine or other accelerating agent being added to the reacting mass and the reaction being interrupted when a sufficiently viscous solution is obtained. Alternatively, the accelerating agent may be added to the impregnating solution when it is required for use. A retarding agent such as weak acid salts of alkali or alkaline earth metals &c. may be added to retain the impregnating solution in a viscous condition until the addition of the accelerating agent. The process may be made continuous, e.g. a roll of fabric may be passed through a machine in which the impregnating material combined with the accelerator is caused to flow on to the fabric, the impregnating material drying in the process of re-rolling or re-folding the fabric.
